A=12(b+c)hA=\frac{1} {2} (b+c) h


Multiply both sides by 2 to do away with a half;


2×A=(b+c)h2×A=(b+c)h


Divide both sides by (b+c)(b+c) so as to remain with the height ;


h(b+c)(b+c)=2A(b+c)h\frac{(b+c) }{(b+c)} =\frac{2A} {(b+c)}


The (b+c)(b+c) on the numerator and denominator will cancel out making the remainder to be ;


h=2A(b+c)h=\frac{2A}{(b+c)}
